GAS-STOVE FOR HEATING.

SPECIFICATION forming part of Letters Patent No. 543,568, dated July 30,1895.

Application filed May 31, 1894- $erial No. 512,992. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS A. BRYAN, a

' citizen of the United States, residing at Baltimore, in the State ofMaryland, have invented certain new and useful Improvements inGas-Stoves for Heating, of which the following is a specification.

This invention relates to a gas-stove for heating rooms.

The object is to provide a stove which shall have combined with it meansfor producing a more perfect combustion of the gas and obtaming moreheat and means for utilizing the light resulting from such combustion.

To this end I have provided a stove of improved construction.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a front elevation of the stove. Fig. 2 is a vertical sectionof the stove. Fig. 3 is a horizontal section of thestove. Fig. 4 is aView of the burner-shell.

The stove-case comprises a base A, a back wall B, two end walls 0, and atop plate D. An upper front plate E extends across near the top betweenthe two end Walls, and a horizontal divisor-plate F is fixed in positionbelow the said top plate D and is in contact with the back wall B andbetween it and the said front plate E, and by this construction aheating-chamber G is formed in the top of the stove. The divisor-plate Fdoes not make contact with the front plate E, but instead its frontedgeturns down, as at a, and a slot or longitudinal opening I) separates thesaid turned-down edge and front plate, and this slot b extends acrossthe entire front. The frontis open below the front plateE and above ahorizontal lowcurb 0, extending crosswise above the base. t

A horizontal bottom plate H separates the base from the upper part ofthe case. This plate has alongitudinal slot 01, and an up flange e isaround the slot. The burner-pipes f project up through this slot, and aburner g is attached to each pipe. All the burner-pipes f lead from aunion-pipe I, which extends horizontally across in front of the base A.A supply-pipe j receives the gas from any source and connects with thesaid union-pipe I. Each burner-pipe has a cut-off cock f to control thegaspassing to the burner g.

Each and all the burners are lnclosed in a I shell L, which is broad atthe bottom k, where it fits over or outside of the upflange c, broad atthe top m, and'provided with upwardly-projecting lips o, where the glassflues P are seated, and narrow at the center n, midway betweensaidbottom and top. Thus each side of the shell has two inclines-an upperincline and a lower incline-which two meet at the narrow center.

The top plate of the shield has openings Z, for a purpose hereinafterstated.

Air-inlets q are in the base below the bottom plate H andthe air entersthere and passes thence up through the slot 01 into the shell L, theair-draft being-contracted at the narrow center a, and just above saidcenter the air supplies the burner.

At one side of the shell L the upper incline has hinges r, and thus saidincline forms and serves as a door S. By tilting this door on its hingesthe burners g are exposed and a lighted match can readily be applied tolight any one of the burners, or all of them, if desired,'with outdisturbing the glass flues.

The glass flues P stand upright upon the top plate of the shell L, oneglass being over each opening I therein and above a burner g. The upperend of each glass flue is inserted through an opening I. in thedivisor-plate F, so that the hot air which passes upward through theglass fines is delivered into the chamber G and after heating saidchamber passes downward and escapes from said chamber through the openslot 19. Thus this part of the heat is utilized by first heating thewalls and top plate D of the chamber, which heat is radiated into theroom, and, second, by the escape of the hot air from the open slot 6. i

The glass flueshere described take the place of metal pipes, which haveheretofore been used in heating-stoves. The glass gives the benefit tothe room of such light or illumination as may result from the combustionof the gas.

A reflector-plate U stands vertically in the back of the stove betweenthe back wall B and the glass flues P. This reflector serves to throwforward the heated air made by the burners and glass fines and projectssuch heated air through the open front into the room.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a gas stove, the combination, witha base, of a case seated thereon, said case comprising, top, bottom,back and end walls, the bottom being slotted longitudinally and providedwith an up-flange around the slot, a bottomless shell fitting over saidflange, the top ofwhich is provided with openings, burners in the shell,one for each opening in the top, a supply pipe communicating with all ofthe burners, and a glass tube from each opening in the shell to theupper portion of the case, substantially as set forth.

2. In a gas stove, the combination, with a base, of a case seatedthereon, said case com prising top, bottom, back and end Walls, thebottom being slotted longitudinally, a bottomless shell fitting over theslot, the top of which is provided with openings and the sides beingcontracted toward each other at the central portion longitudinally ofthe shell, the upper portion of one of the sides of the shell beingformed into a door, burners Within the shell, one for each opening, asupply pipe communieating with all of the burners, and a glass tube fromeach burner to the top portion of the case, the lower end of the tuberesting against the inclined portion of the shell, substantially as setforth.

3. In a gas stove, the combination, with an open front case the top ofwhich is provided with a chamber, the bottom of the chamber beingprovided with openings and extending nearly to the front of the case,whereby a narrow opening is formed at the lower front portion of thechamber, the bottom of the case being slotted longitudinally, abottomless shell over the slot, the top of which is provided withopenings registering with the openings at the bottom of the chamber atthe top of the case, and the side walls are contracted toward each otherat the central portion, longitudinally of the shell, burners within theshell, one for each opening, a supply pipe for the burners, a glass tubefitting within the opening over each burner, with its lower end restingagainst the inclined portion of the shell, and having its upper endprojecting through the opening in the bottom of the chamber at thebottom of the case, substantially as set forth.

In testimony whereof I affix my signature in the presence of twowitnesses.

THOMAS A. BRYAN.
